Wasn't sure where else to post this, but here's a comprehensive Speed Tiers for ADV OU. The list covers all Speed investments featured in each mon's analyses. Bold pink denotes important Speed benchmarks. Green text denotes Speed ties. LMK if you catch any errors or omissions. Credit to McMeghan for his 2020 Speed Tiers, which I'm sure we've all made good use of over the years, and to quote the wise man himself: "Keep in mind that HP Fighting, HP Fire and HP Rock will always reduce your Speed IV".
